Actually the photo was from an auction I found a while ago so sadly no friend to borrow from. Sorry to be confusing. However, I think you have given me the key and I'll try to trace wires beyond this point inside the chassis, especially if it's that simple.
Correction: in your reply, you used 24 VAC in two places but 24 VDC in another. Is this a simple transformer (i.e. AC to AC) or do the lamps need DC voltage?
